Hello Eric,

>The Item property of the Rows collection returns an Object datatype by default. You have to cast this value into the datatype you need (from Object to Single in your case).



If the Item property returns an Object DataType why then the expression
(MyTable.Rows[0]["age"].GetType()) returns System.Single. I would expect Object instead, or am I mixing things?

Thank you.
